. This invention relates to a closure for a container for liquids,pa'stes and the like, and is an improvement over the closure disclosedin the copending application led by me jointly with Benjamin?. Remy onJanuary 14, 1933, Serial No. 651,776, entitled Closure for containers.

The object of the invention, and as set forth in theabove-mentionedapplication, is to provide a sealed closure which isfluid-tight when closed, 1o and which may be conveniently opened andclosed by a slight turning movement of the cap without removing any partthereof from the container. Furthermore, it embodies a non-removable capwhich when in one position closes and seals the nozzle of the container,and while. in the other position is retracted to permit the nozzle toprotrude therethrough so that the cap will not become fouled by thecontents of the container when discharged.

The present invention resides in the structural features of the closure,wherein it is simple in design, compact, sturdy and cheap to manufacturein quantity production.A It will be appreciated that in closures of thistype three essential features are involved to make it commerciallypractical and of benefit -to the public.

Firstly, the closure must be compact and conveniently small so as not toloom bulkily over the container, particularly wherein the public isaccustomed to comparatively small closures. This is accomplished bypermitting the sealing valve to move downwardly to one side between thecap and nozzle rather than be swung laterally so as to requiresubstantial space between the cap and nozzle.

Secondly, it is essential that the structure be rugged and fool-proofsince the constant operation thereof in opening and closing thecontainer should not affect its working parts to such a degree as maydestroy its usefulness and thereby the usefulness of the containerbefore it is emptied of the contents.

Thirdly, and perhaps most important, the closure must be so designed asto permit of very cheap quantity production. In many instances thecontainers themselves are produced for only a few cents and the usualclosures therefor for small fractions of a cent. Therefore, forcommercial purposes, and to obtain any'practical benefit to the public,a closure of this character must be produced within a reasonable. marginof the cost of the container and the usual type of cap or closure.

The full nature of the invention will be un derstood from theaccompanying drawing and the following description and claims:

In the drawing, Fig. 1 is a top plan view of the closure mounted on theend of a collapsible tube. Fig. 2 is an enlarged view showing the 5 lefthalf of the upper end of the tube and nozzle in central vertical sectionwith the right half in elevation. Fig. 3 is an enlarged view showing theclosure mounted on the tube and nozzle in open or discharging position.Fig. 4 is the same as Fig. 3 showing the closure in closed position.Fig. 5 is a section taken on the line 5-5 of Fig. 4.

In the drawing there is illustrated a collapsible tube I0 having itslower end spread out as indicated at II to provide a permanent bottomclosure. The upper end of the tube is formed with a neck I2 and adischarge nozzle I3, the nozzle being surrounded by an annular cup I4about which the closure is secured. The closure comprises a cap I5having a knurled side wall indicated at I6, and a central aperture inthe top indicated at I1 through which the nozzle I3 is adapted toprotrude when in open position, as illustrated in Fig. 3.

Frictionally secured within the cap I5 there is a compressible band I8having split ends, as indicated at I9 in Fig. 5, to permit the band tobe compressed within the cap I5 and expand therein to secure thestructure in position. Said band is provided on opposite sides thereofwith inwardly extending bosses 20 adapted to extend through a cam-likeslot 2I formed aboutr the opposite side walls of a collar 22. The collar22 is formed about its lower edge with a series of teeth 23 adapted tosurround the cup I4 and extend into a groove 24 thereof to be crimpedand secured thereabout for locking the closure on the container. Saidcollar is provided with freeiends, as indicated at 22a, for permittingit to be compressed within the compressible band I8.

Mounted within the collar 22 and pivotally supported upon the bosses 20there is a valve cap 25 provided with a cork insert 26, said valve capbeing concave to extend over the open end of the nozzle I3 for sealingthe same. The cap terminates in a pair of downwardly curved arms 21through which the bosses 2D extend toA provide the pivotal support forthe valve. Each of said arms is provided with a"cut away portionproviding shoulders 28 adapted to be engaged in the actuation of theclosure by the inwardly provjecting lugs 29 for manipulating the valve,as hereinafter described.

In operation, assuming that the closure is in the container is heldxedly with one hand, while the foreiinger and thumb are placed about theknurled surface of the cap l5, which is thereby turned counterclockwiseto open the closure. In thus turning the cap, the collar remainingstationary, the bosses 20, extending from the cap through the slots 2|in the collar, are carried throughout the length of their respective camslots 2| in the stationary collar. As will be noted in Fig. 4, the firstcounterclockwise movement carries the bosses upwardly in the initialupwardly extending portions of the slots 2| which acts to lift the capand valve free of the nozzle. Continued counterclockwise movementcarries the bosses through the laterally-extending portions of the slots2|, to a. position where the lugs 29 are within the recess of theshoulders 28 formed in the arms of the valve. Continued movement causesthe shoulders 28 to engage the lugs 29, wherebyfurther relative movementbetween the shoulders 28 and lugs 29 act to swing the valve cap 25 aboutthe pivotal mounting of the lugs to the position shown in Fig. 3.Further counterclockwise movement causes the bosses 20 to travel throughthe downwardly-extending portion of the cam slots 2| to lower the capand permit the uncovered end of the nozzle to protrude through theaperture I1 to permit free discharge of the contents without fouling theclosure.

By a clockwise rotation, the reverse action takes place, the captravelling upwardly until the top thereof extends overthe top of thenozzle,

whereupon the lugs 29 are engaged by the oppo-y site shoulders 28 toswing the cap 25 upwardly over the end of the nozzle. Continuedclockwise movement causes the bosses to pass through thedownwardly-extending portion of their respective cam slots to cause thevalve cap to be drawn tightly over the nozzle so that the cork gasket 26is held in sealed engagement therewith.
